I currently own a 2000 s2000 and am in the process of building an f20c motor for boost. I want to upgrade to a newer year but was wondering if anyone knows of a few people already doing an ap2 car with ap1 drivetrain setup. I was wondering if the rear end ratios are the same for the ap2 and ap1 and how similar are the trans. will ap2 trans bolt up to ap1 engine? if anyone knows any info it'd be much appreciated
